Rookie Will Smith hit a walk-off home run in his fourth career game as the Los Angeles Dodgers remained undefeated in Clayton Kershaw starts with a 4-3 victory Saturday over the visiting Philadelphia Phillies. Smith, who was called up this week when Austin Barnes went on the injured list, lifted a full-count split-finger pitch from Hector Neris (1-2) in the ninth inning into the left-field corner for his first career home run. The Dodgers won for the eighth time in their last nine games.
